The nearest that I have seen was produced by a now obsolete camera, the Kodak/Nikon DCS200C. The TIFF files from that camera were very course with every sensor photosite represented as it's Bayer mask color. So there were red, blue and green pixels that had not been "demosaiced". When viewed from a distance the images looked reasonable, but any close inspection showed the bare uninterpolated pixels.

And... ? If you had glanced over images in this thread you would have seen several more recent examples.
